c# - Entity Framework 重用连接

Question

在 using block 中用于连接到实体，

调用另一个方法时如何重用连接？

所以我有:

using (SampleEntities entities = new SampleEntities()) {
    entities.Connection.Open();
    SomeMethod();

    ...
}


void SomeMethod() {
   using (SampleEntities entities = new SampleEntities())
   {
      // I want to be able to use the existing connection before the method call, any ideas?
   }

}

Answer 1

为什么没有

 void SomeMethod(SampleEnities context)

并传入；让第一个“使用”来解决处置问题。
